ABOUT RENEWAIRE
For over 30 years, RenewAire has been a pioneer in enhancing indoor air quality (IAQ) in commercial
and residential buildings of every size. This is achieved while maximizing sustainability through our fifth-
generation, static-plate, enthalpic-core Energy Recovery Ventilators (ERVs) that optimize energy efficiency,
lower capital costs via load reduction and decrease operational expenses by minimizing equipment needs,
resulting in significant energy savings. Our ERVs are competitively priced, simple to install, easy to use and
maintain and have a quick payback. They also enjoy the industry’s best warranty with the lowest claims due
to long-term reliability derived from innovative design practices, expert workmanship and Quick Response
Manufacturing (QRM).
As the pioneer of static-plate core technology in North America, RenewAire is the largest ERV producer in the
USA. We’re committed to sustainable manufacturing and lessening our environmental footprint, and to that
end our Madison, WI plant is 100% powered by wind turbines. The facility is also one of the few buildings
worldwide to be LEED and Green Globes certified, as well as having achieved ENERGY STAR Building status.
In 2010, RenewAire joined the Soler & Palau (S&P) Ventilation Group in order to provide direct access to the
latest in energy-efficient air-moving technologies. For more information, visit: renewaire.com.

When an external 10VDC source control is used
the maximum distance between ECM motor and
10VDC source control cannot exceed 33 feet (10m).
CAUTION
ECM MOTORS
RenewAire’s light commercial units are offered
with optional electronically commutated motors
(ECM). ECM motors have higher efficiencies with
considerable energy savings over a standard
permanent split capacitor motor. The ECM motors
offered in RenewAire ERVs are constant torque
with a variety of speed control options. The motors
operate at fixed speed or variable speed with
speed inputs from fixed resistors, potentiometer,
or 0-10Vdc analog signal.
OPERATING CONTROLS
A wide variety of low voltage (24VAC) control
schemes may be selected to meet the ventilation
needs of the facility. These include time clock,
occupancy sensor, carbon dioxide sensor, and
others. Building Management Systems (BMS) may
also control the unit with external control by others.

PLANNING
YOUR INSTALLATION
INSTALLATION
To avoid motor bearing damage
and noisy and/or unbalanced
impellers, keep drywall spray,
construction dust, etc., out of unit.
CAUTION
1. Before servicing or cleaning the unit, switch
power off at disconnect switch or service panel
and lockout/tag-out to prevent power from being
switched on accidentally. More than one discon-
nect switch may be required to de-energize the
equipment for servicing.
2. This installation manual shows the suggested
installation method. Additional measures may be
required by local codes and standards.
3. Installation work and electrical wiring must be
done by qualified professional(s) in accordance
with all applicable codes, standards and
licensing requirements.
4. Any structural alterations necessary for instal-
lation must comply with all applicable building,
health, and safety code requirements.
5. This unit must be grounded.
6. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of
fuel burning equipment that might be installed in
the area affected by this equipment. If this unit
is exhausting air from a space in which chim-
neyvented fuel burning equipment is located,
take steps to assure that combustion air supply
is not affected. Follow the heating equipment
manufacturer’s requirements and the combustion
air supply requirements of applicable codes and
standards.
7. Use the unit only in the manner intended by the
manufacturer. If you have questions, contact
the manufacturer.
8. This unit is intended for general ventilating only.
Do not use to exhaust hazardous or explosive
materials and vapors. Do not connect this unit to
range hoods, fume hoods or collection systems
for toxics.
9. When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
10. If installed indoors this unit must be properly
ducted to the outdoors.
RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:
WARNING
PRINCIPLES OF EXTERNAL CONTROL
The light commercial units with ECM motors are
designed for control by a wide variety of low voltage
(24VAC) controls to meet the ventilation needs of the
facility. These include time clock, occupancy sensor,
carbon dioxide sensor, building management system
(BMS) and others. These devices are commonly
known as 2-wire, 3-wire, and 4-wire devices. Re-
newAire offers separately the following for standalone
control of the ERV:
• Digital Time Clocks TC7D-W and TC7D-E
• Occupancy Sensors MC-C and MC-W
• Carbon Dioxide Sensor/Controllers CO2-W
and CO2-D
HE1X & HE1.5X ONLY
The external control device connects to the Light
Commercial unit to operate each blower independent-
ly or for one blower to act as leader and the other
blower to act as follower. When operating inde-
pendently, a single external switch or relay calls for
operation but each speed control motor can respond
independently to switch or analog signal source.
When acting as leader-follower, again, a single
external source calls for operation and then one motor
responds to the input signal. The Light Commercial
HE1X & HE1.5X units have the versatility that either
the exhaust air (EA) motor or the fresh air (FA) motor
can act as leader. Connection of an external control
device to the Light Commercial Unit is simple. All
external control device wires connect to a terminal
block(s) in the unit’s electrical box.

AIRFLOW PERFORMANCE
The ERV is factory wired to operate at low fixed
speed and high variable speed.
Airflows must be measured and the unit’s potenti-
ometers adjusted so that it operates at the airflow
volumes specified for the installation.
Use the pressure taps in the core and filter doors
to determine the airflow. Figure 1 translates the
pressure drop across the energy recovery core to
the actual airflow volume.
Very low airflow rates may result in fouling of the
energy exchanger core. Do not reduce airflow to below
250 cfm per core.
CAUTION
Make sure clean filters are installed before balancing airflow.
Dirty or clogged filters reduce airflow through the unit.
CAUTION
MEASURING AIRFLOW
Equipment Required
• Magnehelic gauge or other device capable of
measuring 0-1.5 in. water of differential pressure.
• 2 pieces of flexible tubing, 1/8” ID, 1/16” wall
works best.
NOTE: Be sure to remove cap from pressure port
before inserting tubing. Insure tubing is well seated
in pressure ports.
NOTE: The tubing should extend in the pressure
port approximately 1 inch.
Cross Core Static Pressure Measurement
Instructions
• The individual differential static pressures (DP)
are measured using the installed pressure ports
located in the front of the units core access doors.
NOTE: These ports are carefully located on the unit
to give the most accurate airflow measurement.
NOTE: Do not relocate pressure ports.
• To read SCFM of Fresh Air (FA) install the “high”
pressure side (+) of your measuring device to the
Outside Air (OA) port and the “low” pressure side
(-) to the Fresh Air (FA) port.
• To read SCFM of Room Air (RA) install the “high”
pressure side (+) of your measuring device to the
Room Air (RA) port and the “low” pressure side
(-) to the Exhaust Air (EA) port.
• Use the reading displayed on your measurement
device to cross reference the CFM output using
the conversion chart.
NOTE: Be sure to replace cap into pressure port
when air flow measuring is completed.
• Adjust air flow by changing the potentiometer
setting for the measured airstream.
NOTE: For best performance the airflow rate for
both the Fresh Air and the Exhaust Air should be
roughly equal (“balanced”). In some facilities a
slight positive or negative pressure in the building
is desired. RenewAire energy recovery ventilators
can generally operate with a flow imbalance of up
to 20% without significant loss in energy recovery
efficiency.
